A POSIX-compliant Unix shell built from scratch in C — one of 1337's most demanding system programming projects. Handles 20+ built-in commands, multi-stage pipe chains, heredocs, and complex quoted-string parsing, with correct signal routing and zero memory leaks (Valgrind-verified).

A fully playable 2D top-down game built in C with the MLX42 graphics library. Implemented from scratch: tile-based map parsing, a flood-fill solvability check, sprite animation, collision detection, and a fixed-timestep game loop — all with zero memory leaks.

Designed and shipped a production REST API feature at Aura Prestige — integrating a third-party provider with retry logic and error boundaries. Embedded in a professional Agile team: daily stand-ups, PR reviews, and sprint planning from day one.

An interactive browser tool to visualise classic sorting and graph algorithms step by step. Built to bridge the gap between mathematical theory and computational implementation — great for learning and demonstrating algorithmic thinking.

A system administration project requiring a complete multi-service infrastructure inside Docker. Each service runs in its own container — NGINX as TLS reverse proxy, WordPress with php-fpm, and MariaDB as the persistent database — all orchestrated via docker-compose with custom volumes and networks.

A fully compliant IRC server built in C++ from scratch, without using any external libraries. Supports multiple simultaneous clients, channel management, operator privileges, and real IRC commands — compatible with standard IRC clients like irssi.

The final and most ambitious 1337 project — a full-stack multiplayer Pong platform. Built as a single-page application with real-time gameplay, live chat, a friends system, match history, and OAuth2 authentication, all running in a Dockerized environment.
